# Repolyze

> Know your code better.

Repolyze is a Rust CLI/TUI tool for analyzing local Git repositories. All analysis runs locally — no data leaves your machine.

## What it does

- Contributor statistics: commits, lines added/deleted, net contribution, files touched, active days per contributor
- Activity heatmaps: GitHub-style contribution grid showing daily commit intensity over the past year
- File metrics: .gitignore-aware repo walking, file/line/byte counting, extension breakdowns
- Multi-repo analysis: analyze one or many repositories in a single run with batch processing
- Repository comparison: side-by-side ranking of repositories by commits per day with per-weekday breakdowns
- User effort view: per-contributor deep-dive with commit frequency by weekday and hour
- Smart caching: SQLite-backed cache so re-analyzing unchanged repos is instant
- Export formats: JSON, Markdown, and plain-text table output

## Who it's for

- Team leads tracking contributor effort across repositories
- Tech leads comparing codebases and making data-driven decisions about engineering portfolios
- Individual contributors understanding their own contribution patterns

## Installation

- macOS (Homebrew): brew install maximgorbatyuk/tap/repolyze
- Cross-platform (Cargo): cargo install repolyze
- Supported platforms: macOS (Apple Silicon & Intel), Linux x86_64
